The nurse knows that which indwelling catheter procedure places the patient at greatest risk of acquiring a urinary tract infection?
Kinking the catheter tubing to obtain a urine specimen
Emptying the drainage bag every 8 hours or when half full
Failing to secure the catheter tubing to the patient's thigh
Placing the drainage bag on the side rail of the patient's bed
The Correct Answer is D
a) Kinking the catheter tubing to obtain a urine specimen: Kinking the catheter tubing can cause backflow of urine, increasing the risk of infection, but it is not as significant a risk factor as improper drainage bag positioning.
b) Emptying the drainage bag every 8 hours or when half full: Properly emptying the drainage bag regularly reduces the risk of infection, as it prevents overfilling and backflow. This practice is usually part of proper care.
c) Failing to secure the catheter tubing to the patient's thigh: Securing the tubing to the thigh is important for preventing pulling or tension, but it’s not as significant in terms of infection risk as the positioning of the drainage bag.
d) Placing the drainage bag on the side rail of the patient's bed: This significantly increases the risk of urinary tract infections (UTIs) as it can cause the urine to flow back into the bladder, a condition called "reflux." The drainage bag should always be kept below the level of the bladder.

Correct Answer is A
Explanation
a) Neuromuscular problems may result in the client finding urinary control too much trouble, resulting in incontinence: Neuromuscular issues in older adults can affect their ability to control the bladder, leading to urinary incontinence due to weakened bladder muscles and impaired coordination of the sphincter.
b) Increased bladder muscle tone may reduce the capacity of the bladder to hold urine, resulting in frequency: Typically, aging results in decreased bladder muscle tone, not increased, leading to reduced capacity and increased frequency of urination. Increased tone would not typically cause frequency.
c) Decreased bladder contractility may lead to urine retention and stasis, which increases the likelihood of urinary tract infection: Aging can lead to decreased bladder contractility, resulting in urine retention, which can cause stasis and increase the risk of urinary tract infections (UTIs).
d) The diminished ability of the kidneys to concentrate urine may result in urinary tract infection: While diminished kidney function may cause issues like dehydration or nocturia, it is not directly related to causing UTIs. UTIs are more commonly caused by poor urine flow or retention.
Correct Answer is D
Explanation
a) Chloride 100 mEq/L: A chloride level of 100 mEq/L is within the normal range (98-107 mEq/L) and would not be concerning in this context.
b) Sodium 138 mEq/L: A sodium level of 138 mEq/L is within the normal range (135-145 mEq/L) and would not be concerning in this context.
c) Potassium 4.1 mEq/L: A potassium level of 4.1 mEq/L is within the normal range (3.5-5.0 mEq/L) and would not be concerning in this context.
d) Magnesium 1.0 mEq/L: A magnesium level of 1.0 mEq/L is low (normal range: 1.5-2.5 mEq/L), and low magnesium can cause neuromuscular symptoms such as tremors. This would be a concerning result in the context of the patient's hand and face tremors.
